Re: [Xen-users] Bridging and VLANs 802.1Q trunk

Hi

It does not work. You can get the VLAN tagging working with standard network 
sripts. Greg has  made some good examples.

However the traffic does not go through without the patch for the ethtool. I 
hope that someone would put the modifications to standard package. I never 
managed to create rpm-package with required modifications.

i believe (can be wrong) that the xen scripts have two main parts: one for 
initial setup, and one for adding each domU to the right bridges.

try to totally disable the initial setup script.  don't let it confuse 
anything.  then write your own script that sets all the VLAN devices, and all 
needed bridges.  try to make it set all you need, ready to receive the domU's 
vifs.  then the second part of the Xen scripts should work with little or no 
modifications.

after you get it working, it might be wise to add some of the usual xen 
renaming scheme to your initial script, and replace the Xen provided with 
yours.
